Certainly nothing written in stone at this time; but trends appear to indicate that best chances for somewhat higher snow amounts would be as one heads northeast with lesser amounts to the southwest...

If I were betting I would be all in that there`s more snow from I 80 northward once East of the MTNS , but I would  be all in as well if the bet was A WHIFF  here .

The CIPS analogs are useless but also very telling today....the 96 and 120 hour panels did not come in but when you click on the 72 hour panel you see two different scenarios...clicking the Midwest/N Plains box you get no past snow events for us and mainly SW flow events that in no way really match this storm, but when you click down in the S Plains box you see PHL-TTN roughly being the cutoff for the historical snow events and its more Miller B type deals...basically sums up what we all knew already, the GFS is probably smashing the southern energy too much.

a known bias it has. its a crap shoot still by far, its one of those time meteorology over modelology comes into play with where the current players are

Be patient , Not gona miss .The models have to figure out the speed between the southern and northern stream and how fast they phase and

the depth of the PV placement  .  96 hours is a long time in modeling , the spray will narrow  better once at  48 .

I have never seen a storm from 5 days out get modeled 100 perc correct with 100 perc agreement between all models .

Even the great ones make ur knees wobble a day or 2 out .

There`s variance inside great storms at 36 hours at times . Easy to look at flip flop runs and jump off .

Wait if this doesn't look better in a day or 2 then take that approach .

Feb 2006 blizzard was balls on 6 days out, but that was nothing like what we have this week.

Although not a winter storm, Sandy was nailed by the models like 6 days out as well...and to make that historic left turn to boot...

Some systems are easier to nail in the medium range than others. The ECMWF correctly recognized how an extreme block would influence the steering currents that would turn Sandy toward U.S. landfall. The current situation is far more complex.

I do use sandy as an example of how deadly accurate the EURO could be. once it locked onto AC, NJ landfall It set the bar where the rest of the models had to follow. it did spectacular. However, like you said ALOT more complex situation right now and is a mess to say the least :bag:

one reason its more complex is the energy is still located close to a 500 or more miles west of the left coast - sandy was in a better sampling area I do believe for the models

it was it was in the atlantic not like you said WAY off the pacific coast. although I do believe there is still pretty good sampling in that area over lets say Canada where the sampling can be sparse and have drastic effects on the models "cough cough boxing day 2010" :axe:  :lmao:

Not only that but it was a hurricane. The only thing to figure out was how strong would it be and where it was going. Even then many of the models got it wrong and I don't know if any showed our area only getting like an inch of rain. Nailing the details 6 days out is pretty rare.

You can tell when those snow maps are fouled up...like the 18z GFS having 8 to 10 inches in Groton, CT (a stone's throw from Block Island) and 1 to 2 inches in Port Jeff...the only time that sort of thing has a snowball's chance in hell of happening is if we had a Low well offshore that was expected to scrape the coast...and not one where precip type is in question...

here is an animation of what is coming this way from the pacific

That thing in the Pacific is going to make me snowblow on Thursday ??  Ear plugs ready, stabilizer ready, gas ready, pull the cord ... Let's snow blow and get to the storm, if it happens.  WSW or WWA ????

WAY too early to be asking questions like that. we'll not be able to know what this storm is going to do by atleast tomorrow night or Tuesday the way the models are handling these vorts, PV and block

This run still looks disjointed and the confluent shortwave on the south side of the PV is still lifting out faster than the prior runs. 

 

Nothing arguing, to me, that the primary low won't drive just as far north as the prior NAM run which when extrapolated onto the DGEX scheme was quite warm. 

 

That said, the changes in many regards are quite significant on the NAM so far (shocker there, I know). Speaks to the uncertainty of the setup as a whole.

so what this accomplished was that we are still FAR from a conclusion with the substantial model uncertainty today
